But hopefully we will have global education on a level where everyone can make an informed decision on what to believe.

And that education will include the full range of choices, religious instruction, as well as the secular options.

In all fairness, you wouldn't exclude one of the options in a public education environment, and then expect an individual to make an informed choice.

Education ABOUT relgions, sure. Kirk, Picard and other characters in the show were well versed in historical and cultural backgrounds.
But education as in school and knowledge must be secular.
As soon as people are aware of the other options and get some background information they are free to learn more about the individual relgious teachings from the religion itself.

We don't really have to go into the topic of why religious teachings in schools is not the way to go, right?
